US 12,654,000 B2 · Method for producing a bearing arrangement for an implantable blood pump, bearing arrangement and implantable blood pump

Abstract

A method is provided for producing a bearing arrangement for an implantable blood pump. A bearing arrangement and an implantable blood pump are also provided. In the method, a rotor may be provided having one or more drive magnets. The rotor has a conveying element. In addition, a stator having stator windings is provided. Furthermore, the rotor is arranged in a flow channel formed by an inside wall of the stator. A rotor rotation is then driven. While the rotor rotation is driven, a deflection of the rotor is determined. In addition, the deflection of the rotor may be corrected by applying, removing, magnetizing and/or demagnetizing magnetically active material on the stator and/or on the rotor in a non-rotationally symmetrical manner.

A method for producing a bearing arrangement for an implantable blood pump, comprising:

providing a rotor having one or more drive magnets, wherein the rotor has a conveying element,
providing a stator having stator windings,
arranging the rotor in a flow channel formed by an inner wall of the stator,
driving the rotor in rotation,
determining a deflection of the rotor while the rotor is being driven in rotation,
correcting the deflection of the rotor by:
non-rotationally symmetrical application of magnetically active material on the stator, and/or
non-rotationally symmetrical application of magnetically active material on the rotor having one or more drive magnets, and/or
non-rotationally symmetrical removal of magnetically active material from the stator, and/or
non-rotationally symmetrical removal of magnetically active material from a drive magnet of the rotor.
